Parental Controls should be used to restrict access to Windows Vista, selected applications and the Internet for children that either share the computer with their parents or have their own computer. It is in my opinion very important to give your children a restricted user account instead of letting them use an administrative account or your own account. Parental Controls make it possible to add time limits for the usage, block or allow certain applications, allow only games that are suitable for the age of your children and use a filter for the Internet.
